The center of mass of a pitched baseball of radius 3.48 cm moves at 29.4 m/s. The ball spins about an axis through its center of mass with an angular speed of 140 rad/s. Treat the baseball as if it is a solid sphere rotating about its center (I = 2/5MR²).

Calculate the ratio of the rotational energy to the translational kinetic energy.
